Q60. How is overall efficiency of a thermal power plant expressed using major components?
[SSC JE Electrical, 05 June 2024 Shift 3]
(A) Carnot efficiency alone
(B) Rankine efficiency alone
(C) Regenerative-cycle efficiency alone
(D) Boiler efficiency × turbine efficiency × generator efficiency
Answer: (D) Boiler efficiency × turbine efficiency × generator efficiency
Explanation: A conventional steam thermal station converts fuel energy to steam heat, turbine shaft work and electrical output. Multiplying the efficiencies of the boiler, turbine and generator gives an approximation of the full conversion-chain efficiency.
Q59. Which government company developed India’s 500 MWe Prototype Fast Breeder Reactor project at Kalpakkam?
[APPSC Group-I Prelims, 17 March 2024]
(A) BARC
(B) CIMFR
(C) IGCAR
(D) BHAVINI
Answer: (D) BHAVINI
Explanation: Bharatiya Nabhikiya Vidyut Nigam Limited, or BHAVINI, is responsible for construction and commissioning of the Kalpakkam PFBR. IGCAR contributes key research and design expertise, a distinction frequently tested in nuclear-energy questions.
Q58. In which year was the Indira Gandhi Centre for Atomic Research established?
[MPTET Varg 3, 14 November 2024 Shift 1]
(A) 1963
(B) 1968
(C) 1971
(D) 1978
Answer: (C) 1971
Explanation: IGCAR was established in 1971 at Kalpakkam in Tamil Nadu. It conducts advanced nuclear research, especially in fast-reactor technology and associated fuel cycles, in support of India’s wider three-stage atomic energy programme.
Q57. Marwa (Madwa) thermal power station was established in which Chhattisgarh district?
[CGPSC Prelims General Studies, 2023]
(A) Kawardha
(B) Janjgir-Champa
(C) Korba
(D) Surguja
Answer: (B) Janjgir-Champa
Explanation: The Marwa–Tendubhata thermal power project is in Janjgir-Champa district, Chhattisgarh. Its coal-based generating units contribute to the state’s electricity supply and are distinct from the better-known NTPC Korba project.
Q56. Bihar’s first floating solar power plant was constructed at which place?
[68th BPSC Prelims, 12 February 2023]
(A) Kadirabad, Darbhanga
(B) Dilbarpur, Darbhanga
(C) Jamalpur, Darbhanga
(D) More than one of the above
Answer: (A) Kadirabad, Darbhanga
Explanation: The first floating solar installation cited in Bihar state GK is at Kadirabad in Darbhanga. Floating photovoltaic panels occupy water surfaces and provide another way of expanding solar capacity where open land is constrained.
Q55. Which is the largest onshore wind farm in India among these options?
[MP Forest Guard and Jail Prahari, 19 June 2023 Shift 1]
(A) Muppandal Wind Farm
(B) Alta Wind Energy Center
(C) Jaisalmer Wind Park
(D) Los Vientos Wind Farm
Answer: (A) Muppandal Wind Farm
Explanation: Muppandal Wind Farm in Tamil Nadu’s Kanyakumari district is a leading Indian onshore wind cluster. The Aralvaimozhi mountain pass channels strong winds, making the area particularly suitable for turbine installations.
Q54. BARC researchers reported elevated background radiation in certain areas of which state in March 2023?
[SSC CHSL 2022 Tier-II, held 26 June 2023]
(A) Himachal Pradesh
(B) Rajasthan
(C) Kerala
(D) Madhya Pradesh
Answer: (C) Kerala
Explanation: A BARC study examined natural background radiation across India and reported particularly high levels in parts of Kerala. Naturally occurring radionuclides in local minerals, especially coastal monazite-rich sands, can influence measured radiation.
Q53. Arrange these thermal power project locations east-to-west: 1 Kota, 2 Namrup, 3 Obra, 4 Parichha.
[Bihar Senior Secondary Teacher Chemistry, 26 August 2023 Shift 2]
(A) 1–2–3–4
(B) 2–4–1–3
(C) 2–3–4–1
(D) More than one of the above
Answer: (C) 2–3–4–1
Explanation: Namrup is in Assam, Obra and Parichha are in Uttar Pradesh, and Kota is in Rajasthan. Reading their longitudes roughly from east to west yields Namrup, Obra, Parichha and Kota.
Q52. Where is the geothermal field Puga Valley located?
[OSSC TGT, 11 March 2023 Shift 2]
(A) Lakshadweep
(B) Andaman and Nicobar Islands
(C) Ladakh
(D) Jammu and Kashmir
Answer: (C) Ladakh
Explanation: Puga Valley is in Ladakh’s Himalayan geothermal belt. It is known for hot springs and high subsurface heat flow, making it an important prospect for geothermal energy development and a recurring location-based question.
Q51. Kawas Thermal Power Station is located in which state?
[SSC MTS 2022 cycle, held 04 May 2023 Shift 1]
(A) Gujarat
(B) Maharashtra
(C) West Bengal
(D) Rajasthan
Answer: (A) Gujarat
Explanation: Kawas is a gas-based power station operated by NTPC near Surat in Gujarat. Gas turbines and steam-cycle heat recovery distinguish such combined-cycle stations from coal-fired thermal power plants elsewhere in the country.
